INPADOC, which stands for International Patent Documentation,[1][notes 1] is a freely available international patent database. It is produced and maintained by the European Patent Office (EPO). INPADOC developed a patent families classification, which groups together patent applications (and issued patents) originating from the same priority document(s). It also provides data about the legal status (pending, issued, abandoned, expired) for patent documents in many countries and for large time periods. Although INPADOC is not comprehensive, it keeps expanding the breadth and the depth of its coverage.
